What would the answer to this question be? A. 40° B. 60° C. 80° D. 100°

Alex777 [14]

Answer:

D. 100°

Step-by-step explanation:

A straight line is 180°. Add 50° and 30° (which is 80°) and subtract the total from 180°.

50 + 30 = 80

180 - 80 = 100

Determine a polynomial that represents the area of the parallelogram. A=

sp2606 [1]

Answer:

4b² - 16

Step-by-step explanation:

The formula to find the area of a parallelogram equals $bh$ , where b = base and h - height. We're given the base as 2b + 4 and the height as 2b - 4.

$(2b+4)*(2b-4)=(2b+4)(2b-4)$
$(2b+4)(2b-4)=(2b)(2b)+(2b)(-4)+(4)(2b)+(4)(-4)$
$4b^2-8b+8b-16$
$4b^2-16$

Therefore, the answer is 4b² - 16.

2. If y = V9 – 3x, determine the value of x for which y will be a real number.

Pepsi [2]

Answer:

x ≤ 3

Step-by-step explanation:

The expression inside the radical ≥ 0, thus

solve

9 - 3x ≥ 0 ( subtract 9 from both sides )

- 3x ≥ - 9

Divide both sides by - 3, reversing the symol as a result of dividing by a negative quantity

x ≤ 3

Any value of x less than or equal to 3 ensures $\sqrt{9-3x}$ is real
